How do I know if my house fan fuse is blown?
You can tell if the fuse is blown because the fan will not even attempt to turn or make any noise. If you ‘fling’ the blades with your hand, still nothing (sometimes that starts them when they are sticking). But if the fan makes a noise like it is trying to start then it isnt the fuse.
Why does the fan switch not turn on?

How can you tell if a fan relay is faulty?
You’ll know the cooling system relay is faulty if the fan works with the substitute relay. You can also measure the relay coil’s resistance. A normal relay’s resistance will read between 40 to 80 ohms. Higher resistance levels warn that the coil has started to fail while lower readings mean the relay has broken down.

What happens when the fuse on a fan melts?
Like the circuit breakers in your house, these fuses are designed to break the electrical connection when too much electricity causes your fan to overheat. When the fuse melts, it breaks the connection and cuts power to the fan. Check the cord and the inside of your fan for this fuse.
